A. The island hopping of land forces to Japan

B. The use of atomic weaponry on Japan

C. The withdrawal of troops from the Pacific

D. The continued firebombing of Japanese cities

Based on the excerpt, President Truman planned to take the use of atomic weaponry on Japan if Japan refused Allied terms of surrender.

Answer: Option B

Explanation:

The Potsdam declaration directed Japan to surrender during the second World War when the document was issued by President of U. S. Harry S. Truman, Prime Minister of UK Winston Churchill and China's chairman named Chiang Kai-Shek. This ultimatum was given to Japanese armed forces and otherwise, consequences were entire devastation of the nation.

The technology which boosted President Truman to declare an alternative for Japan was the usage of the atomic bomb and related weaponries on their nation which was possessed by the United States although this warning was not declared in official documents.
